How can Low Level Light Therapy help you with injury recovery

What is the first thought that comes to mind when you think of a laser? I definitely think of a laser beam cutting through metal. Physiotherapy

So, why is a laser used for physiotherapy treatments? The fact is that low level lasers, or Low Level Light Therapy (LLLT), are a useful treatment in rehabilitation settings and have been used since the 1960s.1
Low level laser is considered a cold laser as it does not heat up the tissue, which means you should not feel a warming sensation.

Actually, you won’t feel anything during the laser treatments other than the laser head touching your skin. It seems odd that the laser has any effect at all considering that it does not feel like anything is happening during the treatment.

How does it work?

You’re probably wondering, how does this work? Is there really a benefit to this treatment in your rehabilitation? Light is used to go through the skin into the body’s tissues. At certain wavelengths the laser light promotes wound healing by:

• Reducing inflammation2
• Increasing tissue building2
• Reduce scarring2
• Reduce cell death3
• Reduce pain4
• Increase functional abilities1

Is it right for your injury?

Low level lasers are beneficial for a wide range of acute and chronic injuries. Physiotherapists often use this modality for treatments to improve your recovery process and reduce the pain you are experiencing. Injuries that benefit from Low Level Laser include, but are not limited to:

• Sprains
• Muscle or ligament tears
• Rheumatoid arthritis
• Osteoarthritis
• Thoracic pain
• Low back pain
• Neck pain
• Tendinopathy
• Neurological disorders
• Edema
• Wound healing

Ask your physiotherapist if low level lasers or Low Level Light Therapy is right for you!
